Mean papilla index score at baseline, 3 months and 6 months of follow-up

Surface	Baseline	3 month	6 month
Mesial M (SD)	1.3 (0.48)	2.7 (0.48)	2.8 (0.63)
Distal M (SD)	1.4 (0.51)	2.5 (0.52)	2.4 (0.69)

M (SD) = mean (standard deviation).

Statistically significant (P < 0.05, non-parametric Wilcoxon paired test) papilla index score changes.
